Siman 181

(15.) "I had a fine body that was not demanding and did not press itself at all. Now I must observe the time of eating etc. And the sufferings I had there are beyond explanation — needless to say the suffering of the mind. I also received remedies and was drinking quinine [china — remedy for fever/malaria] — and there in the land of China they are complete heretics who say there is no judgment and no judge. And similarly other remedies from other places that have other heresies there. And when all of this came inside my innards, what was made was made. For it was necessary that the medicine coming from there should enter his innards in order to subdue those heresies mentioned — and similarly with other medicines." (From this the discerning one will be able to understand something of his dealings with remedies — beyond the other lofty secrets that were in all his ways and conducts. But for the rest of the world he warned very much by way of good counsel to stay far from medicines and doctors.)
